Acre-feet per minute (ac-ft/min)
Cubic yards per second (yd³/s)

Conversion Formula

yd³/s = ac-ft/min × 26.88888889

About Acre-feet per minute

The acre-foot per minute (ac-ft/min) equals 1233.48183754752/60 ≈ 20.558 m³/s, encountered in large irrigation canal capacity descriptions and reservoir emergency spillway sizing in the US West. A major canal gate releasing 1 ac-ft/min drains a 1-acre field 1 foot deep every minute - a substantial agricultural flow. 1 ac-ft/min ≈ 20.558 m³/s ≈ 726.0 ft³/s.

About Cubic yards per second

The cubic yard per second (yd³/s) equals 0.764554857984 m³/s, a large unit used in US civil engineering for river flood-stage measurements and reservoir emergency-spillway capacity. A major dam spillway releasing water at 1 000 yd³/s could drain an Olympic pool in about 3 seconds. 1 yd³/s = 0.764554857984 m³/s ≈ 764.555 L/s ≈ 27 ft³/s.
